The problem you're running into is that most background thread / worker APIs will create the thread in a Multithreaded Apartment state. The error message indicates that the control requires the thread be a Single Threaded Apartment.

You can work around this by creating a thread yourself and specifying the STA apartment state on the thread.

var t = new Thread(MyThreadStartMethod);
t.SetApartmentState(ApartmentState.STA);
t.Start();

for (int i = 0; i < getArray.length(); i++) {
            JSONObject objects = getArray.getJSONObject(i);
            Iterator key = objects.keys();
            while (key.hasNext()) {
                String k = key.next().toString();
                System.out.println("Key : " + k + ", value : "
                        + objects.getString(k));
            }
            // System.out.println(objects.toString());
            System.out.println("-----------");

        }

Hope this helps someone

Try to start mongoDB server by giving the --dbpath with mongod.

sudo mongod --dbpath /var/lib/mongo/data/db &

'&' in the last will start the mongodb server as service on your server.

Hope it Works.

nothing much to add,

1 - if you want to execute a query in a loop (more than 1 time), prepared statement can be faster, because of optimization that you mentioned.

2 - parameterized query is a good way to avoid SQL Injection. Parameterized querys are only available in PreparedStatement.

An array doesn't have an add method. You assign a value to an element of the array with num[i]=value;.

public static void main(String[] args) {
    int[] num = new int[args.length];
    for (int i=0; i < num.length; i++){
      int neki = Integer.parseInt(args[i]);
      num[i]=neki;
    }
}

I have this method, I call it the Derp method for lack of a better name.

while (str.indexOf("  ") !== -1) {
    str = str.replace(/  /g, " ");
}

Running it in JSPerf gives some surprising results.

I had similar Issue where we have GenericResponse object containing list of values

 ResponseEntity<ResponseDTO> responseEntity = restTemplate.exchange(
                redisMatchedDriverUrl,
                HttpMethod.POST,
                requestEntity,
                ResponseDTO.class
        );

Usage of objectMapper helped in converting LinkedHashMap into respective DTO objects

 ObjectMapper mapper = new ObjectMapper();

 List<DriverLocationDTO> driverlocationsList = mapper.convertValue(responseDTO.getData(), new TypeReference<List<DriverLocationDTO>>() { });

You can try this way -

ObjectAnimator.ofFloat(view, "translationX", 100f).apply {
    duration = 2000
    start()
}

Note - view is your view where you want animation.

• Pass a string to RegExp or create a regex using the // syntax
• Call regex.test(string), not string.test(regex)

So

jQuery(function () {
    $(".mail").keyup(function () {
        var VAL = this.value;

        var email = new RegExp('^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$');

        if (email.test(VAL)) {
            alert('Great, you entered an E-Mail-address');
        }
    });
});

If I understand well, you want to Join ScheduleRequest with User and apply the in clause to the userName property of the entity User.

I'd need to work a bit on this schema. But you can try with this trick, that is much more readable than the code you posted, and avoids the Join part (because it handles the Join logic outside the Criteria Query).

List<String> myList = new ArrayList<String> ();
for (User u : usersList) {
    myList.add(u.getUsername());
}
Expression<String> exp = scheduleRequest.get("createdBy");
Predicate predicate = exp.in(myList);
criteria.where(predicate);

In order to write more type-safe code you could also use Metamodel by replacing this line:

Expression<String> exp = scheduleRequest.get("createdBy");

with this:

Expression<String> exp = scheduleRequest.get(ScheduleRequest_.createdBy);

If it works, then you may try to add the Join logic into the Criteria Query. But right now I can't test it, so I prefer to see if somebody else wants to try.

Not a perfect answer though may be code snippets might help.

public <T> List<T> findListWhereInCondition(Class<T> clazz,
            String conditionColumnName, Serializable... conditionColumnValues) {
        QueryBuilder<T> queryBuilder = new QueryBuilder<T>(clazz);
        addWhereInClause(queryBuilder, conditionColumnName,
                conditionColumnValues);
        queryBuilder.select();
        return queryBuilder.getResultList();

    }


private <T> void addWhereInClause(QueryBuilder<T> queryBuilder,
            String conditionColumnName, Serializable... conditionColumnValues) {

        Path<Object> path = queryBuilder.root.get(conditionColumnName);
        In<Object> in = queryBuilder.criteriaBuilder.in(path);
        for (Serializable conditionColumnValue : conditionColumnValues) {
            in.value(conditionColumnValue);
        }
        queryBuilder.criteriaQuery.where(in);

    }

Line breaks character for NSString is \r

correct way to use [NSString StringWithFormat:@"%@\r%@",string1,string2];

\r ----> carriage return

Try setting this before you print:

setvbuf (stdout, NULL, _IONBF, 0);

I have discovered that NotePad++ now also creates a subfolder at the file location, called nppBackup. So if your file lived in a folder called c:/thisfolder have a look to see if there's a folder called c:/thisfolder/nppBackup.

Occasionally I couldn't find the backup in AppData\Roaming\Notepad++\backup, but I found it in nppBackup.

Try gcc -c -I/home/me/development/skia sample.c.

Thank to Brian for the code. I was trying to connect to the sql server with {call spname(?,?)} and I got errors, but when I change my code to exec sp... it works very well.

I post my code in hope this helps others with problems like mine:

ResultSet rs = null;
PreparedStatement cs=null;
Connection conn=getJNDIConnection();

try {
    cs=conn.prepareStatement("exec sp_name ?,?,?,?,?,?,?");
    cs.setEscapeProcessing(true);
    cs.setQueryTimeout(90);

    cs.setString(1, "valueA");

    cs.setString(2, "valueB");

    cs.setString(3, "0418");

    //commented, because no need to register parameters out!, I got results from the resultset. 
    //cs.registerOutParameter(1, Types.VARCHAR);
    //cs.registerOutParameter(2, Types.VARCHAR);

    rs = cs.executeQuery();
    ArrayList<ObjectX> listaObjectX = new ArrayList<ObjectX>();
    while (rs.next()) {

        ObjectX to = new ObjectX();
        to.setFecha(rs.getString(1));
        to.setRefId(rs.getString(2));
        to.setRefNombre(rs.getString(3));
        to.setUrl(rs.getString(4));

        listaObjectX.add(to);

    }
    return listaObjectX;
     } catch (SQLException se) {
        System.out.println("Error al ejecutar SQL"+ se.getMessage());
        se.printStackTrace();
        throw new IllegalArgumentException("Error al ejecutar SQL: " + se.getMessage());

    } finally {

        try {

            rs.close();
            cs.close();
          con.close();

        } catch (SQLException ex) {
            ex.printStackTrace();
        }
    }

So I found a solution. I created an angularJS service, we'll call it MyDataRepository and I created a module for it. I then serve up this javascript file from my server-side controller:

HTML:

<script src="path/myData.js"></script>

Server-side:

@RequestMapping(value="path/myData.js", method=RequestMethod.GET)
public ResponseEntity<String> getMyDataRepositoryJS()
{
    // Populate data that I need into a Map
    Map<String, String> myData = new HashMap<String,String>();
    ...
    // Use Jackson to convert it to JSON
    ObjectMapper mapper = new ObjectMapper();
    String myDataStr = mapper.writeValueAsString(myData);

    // Then create a String that is my javascript file
    String myJS = "'use strict';" +
    "(function() {" +
    "var myDataModule = angular.module('myApp.myData', []);" +
    "myDataModule.service('MyDataRepository', function() {" +
        "var myData = "+myDataStr+";" +
        "return {" +
            "getData: function () {" +
                "return myData;" +
            "}" +
        "}" +
    "});" +
    "})();"

    // Now send it to the client:
    HttpHeaders responseHeaders = new HttpHeaders();
    responseHeaders.add("Content-Type", "text/javascript");
    return new ResponseEntity<String>(myJS , responseHeaders, HttpStatus.OK);
}

I can then inject MyDataRepository where ever I need it:

someOtherModule.service('MyOtherService', function(MyDataRepository) {
    var myData = MyDataRepository.getData();
    // Do what you have to do...
}

This worked great for me, but I am open to any feedback if anyone has any. }

The only correct way that I could do page refresh was through JavaScript, many of top .NET answers failed for me.

Response.Write("<script type='text/javascript'> setTimeout('location.reload(true); ', timeout);</script>");

Put the above code in button click event or anywhere you want to force page refresh.

Posting another script solution DateX (author) for anyone interested

DateX does NOT wrap the original Date object, but instead offers an identical interface with additional methods to format, localise, parse, diff and validate dates easily. So one can just do new DateX(..) instead of new Date(..) or use the lib as date utilities or even as wrapper or replacement around Date class.

The date format used is identical to php date format.

c-like format is also supported (although not fully)

for the example posted (YYYY/mm/dd hh:m:sec) the format to use would be Y/m/d H:i:s eg

var formatted_date = new DateX().format('Y/m/d H:i:s');

or

var formatted_now_date_gmt = new DateX(DateX.UTC()).format('Y/m/d H:i:s');

The solution for me was to stop/start the dnscache on my windows 7 machine. Open a console as administrator and type

net stop dnscache
net start dnscache

then sigh and look for a way to get a Mac as your principal desktop.

Here's a way with gsub:

cs <- c("foo_bar","bar_foo","apple","beer")
gsub('.{3}$', '', cs)
# [1] "foo_" "bar_" "ap"   "b"

Try this:

schtasks /change /ENABLE /tn "Auto Restart" /s mycomutername /u mycomputername\username/p mypassowrd

It appears that at least one of your predictors ,x1, x2, or x3, has only one factor level and hence is a constant.

Have a look at

lapply(dataframe.df[c("x1", "x2", "x3")], unique)

to find the different values.

Try to make git tag it should be enough if not try to make git fetch then git tag.

Not quite sure why the answer above needs to go into benchmarks, string buffers, tests, etc.

Assign a value when declaring the variable.

DECLARE @result VARCHAR(1000) ='';

SELECT @result = CAST(StudentId AS VARCHAR) + ',' FROM Student WHERE condition = xyz

The answer to "Given a class, see if instance has method (Ruby)" is better. Apparently Ruby has this built-in, and I somehow missed it. My answer is left for reference, regardless.

Ruby classes respond to the methods instance_methods and public_instance_methods. In Ruby 1.8, the first lists all instance method names in an array of strings, and the second restricts it to public methods. The second behavior is what you'd most likely want, since respond_to? restricts itself to public methods by default, as well.

Foo.public_instance_methods.include?('bar')

In Ruby 1.9, though, those methods return arrays of symbols.

Foo.public_instance_methods.include?(:bar)

If you're planning on doing this often, you might want to extend Module to include a shortcut method. (It may seem odd to assign this to Module instead of Class, but since that's where the instance_methods methods live, it's best to keep in line with that pattern.)

class Module
  def instance_respond_to?(method_name)
    public_instance_methods.include?(method_name)
  end
end

If you want to support both Ruby 1.8 and Ruby 1.9, that would be a convenient place to add the logic to search for both strings and symbols, as well.

Take a look at this answer: ImportError: no module named win32api

You can use

pip install pypiwin32

Also, other simple alternative could be:

gb = df.groupby("A")
gb.count() # or,
gb.get_group(your_key)

To get back to the parent frame, use:

driver.switchTo().parentFrame();

To get back to the first/main frame, use:

driver.switchTo().defaultContent();

You can use this for 24 hour to 12 hour:

echo date("h:i", strtotime($time));

And for vice versa:

echo date("H:i", strtotime($time));

SELECT *
FROM myTable
WHERE URL = LEFT('mysyte.com/?id=2&region=0&page=1', LEN(URL))

Or use CHARINDEX http://msdn.microsoft.com/en-us/library/aa258228(v=SQL.80).aspx

It waits for client.GetAsync("aaaaa");, but doesn't wait for result = Print(x)

Try responseTask.ContinueWith(x => result = Print(x)).Wait()

--EDIT--

Task responseTask = Task.Run(() => { 
    Thread.Sleep(1000); 
    Console.WriteLine("In task"); 
});
responseTask.ContinueWith(t=>Console.WriteLine("In ContinueWith"));
responseTask.Wait();
Console.WriteLine("End");

Above code doesn't guarantee the output:

In task
In ContinueWith
End

But this does (see the newTask)

Task responseTask = Task.Run(() => { 
    Thread.Sleep(1000); 
    Console.WriteLine("In task"); 
});
Task newTask = responseTask.ContinueWith(t=>Console.WriteLine("In ContinueWith"));
newTask.Wait();
Console.WriteLine("End");

for me shelling-out does the job because it gives you possibility to run [a|any] command on the shell:

http://www.dba-oracle.com/t_display_current_directory_sqlplus.htm

in short see the current directory:

!pwd

change it

!cd /path/you/want

this should be on here: it works anyway. And it looks good compared to the above ones.

hlsl code

        float3 Hue(float H)
        {
            half R = abs(H * 6 - 3) - 1;
            half G = 2 - abs(H * 6 - 2);
            half B = 2 - abs(H * 6 - 4);
            return saturate(half3(R,G,B));
        }

        half4 HSVtoRGB(in half3 HSV)
        {
            return half4(((Hue(HSV.x) - 1) * HSV.y + 1) * HSV.z,1);
        }

float3 is 16 bit precision vector3 data type, i.e. float3 hue() is returns a data type (x,y,z) e.g. (r,g,b), half is same with half precision, 8bit, a float4 is (r,g,b,a) 4 values.

For Visual Basic:

[Enum].GetNames(typeof(MyEnum)).Length did not work with me, but [Enum].GetNames(GetType(Animal_Type)).length did.

class Test
{
    Dictionary<int, string> entities;

    public string GetEntity(int code)
    {
        // java's get method returns null when the key has no mapping
        // so we'll do the same

        string val;
        if (entities.TryGetValue(code, out val))
            return val;
        else
            return null;
    }
}

This one worked for me (just keep it for reference when in need)

We have a winXP build pc, and use Visual Build Pro 6 to build our software. since some of our developers use VS 2010 the project files now contain reference to "tool version 4.0" and from what I can tell, this tells Visual Build it needs to find a sdk7.x somewhere, even though we only build for .NET 3.5. This caused it not to find lc.exe. I tried to fool it by pointing all the macros to the 6.0A sdk that came with VS2008 which is installed on the pc, but that did not work.

I eventually got it working by downloading and installing sdk 7.1. I then created a registry key for 7.0A and pointed the install path to the install path of the 7.1 sdk. now it happily finds a compatible "lc.exe" and all the code compiles fine. I have a feeling I will now also be able to compile .NET 4.0 code even though VS2010 is not installed, but I have not tried that yet.

This may help someone:

This is a little different than just a global replace

from the terminal we run
node replace.js

replace.js:

function processFile(inputFile, repString = "../") {
var fs = require('fs'),
    readline = require('readline'),
    instream = fs.createReadStream(inputFile),
    outstream = new (require('stream'))(),
    rl = readline.createInterface(instream, outstream);
    formatted = '';   

const regex = /<xsl:include href="([^"]*)" \/>$/gm;

rl.on('line', function (line) {
    let url = '';
    let m;
    while ((m = regex.exec(line)) !== null) {
        // This is necessary to avoid infinite loops with zero-width matches
        if (m.index === regex.lastIndex) {
            regex.lastIndex++;
        }
        
        url = m[1];
    }

    let re = new RegExp('^.* <xsl:include href="(.*?)" \/>.*$', 'gm');

    formatted += line.replace(re, `\t<xsl:include href="${repString}${url}" />`);
    formatted += "\n";
});

rl.on('close', function (line) {
    fs.writeFile(inputFile, formatted, 'utf8', function (err) {
        if (err) return console.log(err);
    });

});
}


// path is relative to where your running the command from
processFile('build/some.xslt');

This is what this does. We have several file that have xml:includes

However in development we need the path to move down a level.

From this

<xsl:include href="common/some.xslt" />

to this

<xsl:include href="../common/some.xslt" />

So we end up running two regx patterns one to get the href and the other to write there is probably a better way to do this but it work for now.

Thanks

You should use .Load and not .LoadXML

MSDN Link

"The LoadXml method is for loading an XML string directly. You want to use the Load method instead."

ref : Link

jquery $() function always return non null value - mean elements matched you selector cretaria. If the element was not found it will return an empty array. So your code will look something like this -

if ($("#btext" + i).length){
        //alert($("#btext" + i).text());
    $("#btext" + i).text("Branch " + i);
}

In addition to the answers above, you should initialize the StringBuilder with an appropriate capacity, especially that you already know it. For example:

int capacity = existingString.length() + n * appendableString.length();
StringBuilder builder = new StringBuilder(capacity);

Hi if you are having dropdownlist like this

<select id="testID">
<option value="1">Value1</option>
<option value="2">Value2</option>
<option value="3">Value3</option>
<option value="4">Value4</option>
<option value="5">Value5</option>
<option value="6">Value6</option>
</select>
<input type="button" value="Get dropdown selected Value" onclick="getHTML();">

after giving id to dropdownlist you just need to add jquery code like this

function getHTML()
{
      var display=$('#testID option:selected').html();
      alert(display);
}

I tried these solutions but never got a conclusive result. In the end I used proper semantic markup with a fieldset. It saved having to add any width calculations and any box-sizing.

It also allows you to set the form width as you require and the inputs remain within the padding you need for your edges.

In this example I have put a border on the form and fieldset and an opaque background on the legend and fieldset so you can see how they overlap and sit with each other.

<html>
  <head>
  <style>
    form {
      width: 300px;
      margin: 0 auto;
      border: 1px solid;
    }
    fieldset {
      border: 0;
      margin: 0;
      padding: 0 20px 10px;
      border: 1px solid blue;
      background: rgba(0,0,0,.2);
    }
    legend {
      background: rgba(0,0,0,.2);
      width: 100%;
      margin: 0 -20px;
      padding: 2px 20px;
      color: $col1;
      border: 0;
    }
    input[type="email"],
    input[type="password"],
    button {
      width: 100%;
      margin: 0 0 10px;
      padding: 0 10px;
    }
    input[type="email"],
    input[type="password"] {
      line-height: 22px;
      font-size: 16px;
    }
    button {
    line-height: 26px;
    font-size: 20px;
    }
  </style>
  </head>
  <body>
  <form>
      <fieldset>
          <legend>Log in</legend>
          <p>You may need some content here, a message?</p>
          <input type="email" id="email" name="email" placeholder="Email" value=""/>
          <input type="password" id="password" name="password" placeholder="password" value=""/>

The FragmentManger's function add and replace can be described as these 1. add means it will add the fragment in the fragment back stack and it will show at given frame you are providing like

getFragmentManager.beginTransaction.add(R.id.contentframe,Fragment1.newInstance(),null)

2.replace means that you are replacing the fragment with another fragment at the given frame

getFragmentManager.beginTransaction.replace(R.id.contentframe,Fragment1.newInstance(),null)

The Main utility between the two is that when you are back stacking the replace will refresh the fragment but add will not refresh previous fragment.

You can combine the two functions; coerce to characters thence to numerics:

> fac <- factor(c("1","2","1","2"))

I ran into this when I reduced the number of user-input parameters in userInput from 3 to 1. This changed the variable output type of userInput from an array to a primitive.

Example:

myvar1 = userInput['param1']
myvar2 = userInput['param2']

to:

myvar = userInput

use this function:

    public static string ConvertDataTableToHTML(DataTable dt)
    {
        string html = "<table>";
        //add header row
        html += "<tr>";
        for(int i=0;i<dt.Columns.Count;i++)
            html+="<td>"+dt.Columns[i].ColumnName+"</td>";
        html += "</tr>";
        //add rows
        for (int i = 0; i < dt.Rows.Count; i++)
        {
            html += "<tr>";
            for (int j = 0; j< dt.Columns.Count; j++)
                html += "<td>" + dt.Rows[i][j].ToString() + "</td>";
            html += "</tr>";
        }
        html += "</table>";
        return html;
    }

Select ColumnB and as two CF formula rules apply:

Green: =AND(B1048576="X",B1="Y")

Red: =AND(B1048576="X",B1="W")

Using sed, just for variety:

ls -l | sed -n 2p

Using this alternative, which looks more efficient since it stops reading the input when the required line is printed, may generate a SIGPIPE in the feeding process, which may in turn generate an unwanted error message:

ls -l | sed -n -e '2{p;q}'

I've seen that often enough that I usually use the first (which is easier to type, anyway), though ls is not a command that complains when it gets SIGPIPE.

For a range of lines:

ls -l | sed -n 2,4p

For several ranges of lines:

ls -l | sed -n -e 2,4p -e 20,30p
ls -l | sed -n -e '2,4p;20,30p'

I found a perfect and simple method. The auto layout does not allow you to resize the spaces equally, but it does allow you to resize views equally. Simply put some invisible views in between your fields and tell auto layout to keep them the same size. It works perfectly!

One thing of note though; when I reduced the size in the interface designer, sometimes it got confused and left a label where it was, and it had a conflict if the size was changed by an odd amount. Otherwise it worked perfectly.

edit: I found that the conflict became a problem. Because of that, I took one of the spacing constraints, deleted it and replaced it with two constraints, a greater-than-or-equal and a less-than-or-equal. Both were the same size and had a much lower priority than the other constraints. The result was no further conflict.

As noone posted the code that uses BitConverter and actually checks the endianness, here goes:

byte[] ip = address.Split('.').Select(s => Byte.Parse(s)).ToArray();
if (BitConverter.IsLittleEndian) {
  Array.Reverse(ip);
}
int num = BitConverter.ToInt32(ip, 0);

and back:

byte[] ip = BitConverter.GetBytes(num);
if (BitConverter.IsLittleEndian) {
  Array.Reverse(ip);
}
string address = String.Join(".", ip.Select(n => n.ToString()));

var inputs = events.Select(async ev => await ProcessEventAsync(ev))
                   .Select(t => t.Result)
                   .Where(i => i != null)
                   .ToList();

But this seems very weird to me, first of all the use of async and await in the select. According to this answer by Stephen Cleary I should be able to drop those.

The call to Select is valid. These two lines are essentially identical:

events.Select(async ev => await ProcessEventAsync(ev))
events.Select(ev => ProcessEventAsync(ev))

(There's a minor difference regarding how a synchronous exception would be thrown from ProcessEventAsync, but in the context of this code it doesn't matter at all.)

Then the second Select which selects the result. Doesn't this mean the task isn't async at all and is performed synchronously (so much effort for nothing), or will the task be performed asynchronously and when it's done the rest of the query is executed?

It means that the query is blocking. So it is not really asynchronous.

Breaking it down:

var inputs = events.Select(async ev => await ProcessEventAsync(ev))

will first start an asynchronous operation for each event. Then this line:

                   .Select(t => t.Result)

will wait for those operations to complete one at a time (first it waits for the first event's operation, then the next, then the next, etc).

This is the part I don't care for, because it blocks and also would wrap any exceptions in AggregateException.

and is it completely the same like this?

var tasks = await Task.WhenAll(events.Select(ev => ProcessEventAsync(ev)));
var inputs = tasks.Where(result => result != null).ToList();

var inputs = (await Task.WhenAll(events.Select(ev => ProcessEventAsync(ev))))
                                       .Where(result => result != null).ToList();

Yes, those two examples are equivalent. They both start all asynchronous operations (events.Select(...)), then asynchronously wait for all the operations to complete in any order (await Task.WhenAll(...)), then proceed with the rest of the work (Where...).

Both of these examples are different from the original code. The original code is blocking and will wrap exceptions in AggregateException.

This question is kind of old and in July 2011 Google released the Compatibility Package, revision 3) which includes the ViewPager that works with Android 1.6 upwards. The GestureListener answers posted for this question don't feel very elegant on Android. If you're looking for the code used in switching between photos in the Android Gallery or switching views in the new Play Market app then it's definitely ViewPager.

Here's some links for more info:

• http://android-developers.blogspot.com/2011/08/horizontal-view-swiping-with-viewpager.html
• http://mobile.tutsplus.com/tutorials/android/android-user-interface-design-horizontal-view-paging/
• http://thepseudocoder.wordpress.com/2011/10/05/android-page-swiping-using-viewpager/

It's this easy:

update my_table
set path = replace(path, 'oldstring', 'newstring')

It looks like such kind of errors related to the fact that Visual Studio doesn't provide correct information about an error. The developer doesn't even understand the reason for the failed build. It can be a syntax error or something else. In common, to solve such problems you should find the root of the problem (for example, look at the build log).

In my case the problem was in fact that the Error List window didn't show any errors. But really there were syntax errors; I found these errors in the Output window, and after fixing them, the problem was solved.

@Chaibi Alaa, To make the user able to add only once, and move the marker; You can set the marker on first click and then just change the position on subsequent clicks.

var marker;

google.maps.event.addListener(map, 'click', function(event) {
   placeMarker(event.latLng);
});


function placeMarker(location) {

    if (marker == null)
    {
          marker = new google.maps.Marker({

Just use File.GetLastWriteTime. There's a sample on that page showing how to use it.

In my app, user experience is better if more memory is used, so I have to decide if I really should free all the memory I can in didReceiveMemoryWarning. Based on Split's and Jasper Pol's answer, using a maximum of 45% of the total device memory appears to be a safe threshold (thanks guys).

In case someone wants to look at my actual implementation:

#import "mach/mach.h"

- (void)didReceiveMemoryWarning
{
    // Remember to call super
    [super didReceiveMemoryWarning];

    // If we are using more than 45% of the memory, free even important resources,
    // because the app might be killed by the OS if we don't
    if ([self __getMemoryUsedPer1] > 0.45)
    {
        // Free important resources here
    }

    // Free regular unimportant resources always here
}

- (float)__getMemoryUsedPer1
{
    struct mach_task_basic_info info;
    mach_msg_type_number_t size = sizeof(info);
    kern_return_t kerr = task_info(mach_task_self(), MACH_TASK_BASIC_INFO, (task_info_t)&info, &size);
    if (kerr == KERN_SUCCESS)
    {
        float used_bytes = info.resident_size;
        float total_bytes = [NSProcessInfo processInfo].physicalMemory;
        //NSLog(@"Used: %f MB out of %f MB (%f%%)", used_bytes / 1024.0f / 1024.0f, total_bytes / 1024.0f / 1024.0f, used_bytes * 100.0f / total_bytes);
        return used_bytes / total_bytes;
    }
    return 1;
}

Swift (based on this answer):

func __getMemoryUsedPer1() -> Float
{
    let MACH_TASK_BASIC_INFO_COUNT = (sizeof(mach_task_basic_info_data_t) / sizeof(natural_t))
    let name = mach_task_self_
    let flavor = task_flavor_t(MACH_TASK_BASIC_INFO)
    var size = mach_msg_type_number_t(MACH_TASK_BASIC_INFO_COUNT)
    var infoPointer = UnsafeMutablePointer<mach_task_basic_info>.alloc(1)
    let kerr = task_info(name, flavor, UnsafeMutablePointer(infoPointer), &size)
    let info = infoPointer.move()
    infoPointer.dealloc(1)
    if kerr == KERN_SUCCESS
    {
        var used_bytes: Float = Float(info.resident_size)
        var total_bytes: Float = Float(NSProcessInfo.processInfo().physicalMemory)
        println("Used: \(used_bytes / 1024.0 / 1024.0) MB out of \(total_bytes / 1024.0 / 1024.0) MB (\(used_bytes * 100.0 / total_bytes)%%)")
        return used_bytes / total_bytes
    }
    return 1
}

A simple solution that springs to mind is to have a String block of spaces:

String indent = "                  "; // 20 spaces.

When printing out a string, compute the actual indent and add it to the end:

String output = "Newspaper";
output += indent.substring(0, indent.length - output.length);

This will mediate the number of spaces to the string, and put them all in the same column.

You can try to use btn-sm, btn-xs and btn-lg classes like this:

.btn-xl {
    padding: 10px 20px;
    font-size: 20px;
    border-radius: 10px;
}

JSFIDDLE DEMO

You can make use of Bootstrap .btn-group-justified css class. Or you can simply add:

.btn-xl {
    padding: 10px 20px;
    font-size: 20px;
    border-radius: 10px;
    width:50%;    //Specify your width here
}

How about CAST(2229.999 AS DECIMAL(6,2)) to get a decimal with 2 decimal places

Try this it's simple and fast

SELECT T.name AS [TABLE NAME], I.rows AS [ROWCOUNT] 
FROM   sys.tables AS T 
   INNER JOIN sys.sysindexes AS I ON T.object_id = I.id 
   AND I.indid < 2 ORDER  BY I.rows DESC

Find elements:

var elements = document.getElementsByClassName('widget hover');

Since elements is a live array and reflects all dom changes you can remove all hover classes with a simple while loop:

while(elements.length > 0){
    elements[0].classList.remove('hover');
}

FOR FADE add this first line with your animation's object.

.animate().alpha(1).setDuration(2000);

FOR EXAMPLE

I think you can go with 3 steps:

git clone
git submodule init
git submodule update

None of the examples using jquery in here are actually correct as they will leave the select displaying the first entry even though value has been changed.

The right way to select Alaska and have the select show the right item as selected using:

<select id="state">
    <option value="AL">Alabama</option>
    <option value="AK">Alaska</option>
    <option value="AZ">Arizona</option>
</select>

With jquery would be:

$('#state').val('AK').change();

mbstring is a "non-default" extension, that is not enabled by default ; see this page of the manual :

Installation

mbstring is a non-default extension. This means it is not enabled by default. You must explicitly enable the module with the configure option. See the Install section for details

So, you might have to enable that extension, modifying the php.ini file (and restarting Apache, so your modification is taken into account)

I don't use CentOS, but you may have to install the extension first, using something like this (see this page, for instance, which seems to give a solution) :

yum install php-mbstring

(The package name might be a bit different ; so, use yum search to get it :-) )

It's because you haven't declared outchar before you use it. That means that the compiler will assume it's a function returning an int and taking an undefined number of undefined arguments.

You need to add a prototype pf the function before you use it:

void outchar(char);  /* Prototype (declaration) of a function to be called */  int main(void) {     ... }  void outchar(char ch) {     ... } 

Note the declaration of the main function differs from your code as well. It's actually a part of the official C specification, it must return an int and must take either a void argument or an int and a char** argument.

getCurrentActivity().getFragmentManager()

If Perl is an option, you can try this:

perl -ne 'printf "%s,$_" , $.-1' file

$_ is the line
$. is the line number

For example:

String myInput = null;
Scanner myscan = new Scanner(System.in).useDelimiter("\\n");
System.out.println("Enter your input: ");
myInput = myscan.next();
System.out.println(myInput);

This will let you use Enter as a delimiter.

Thus, if you input:

Hello world (ENTER)

it will print 'Hello World'.

I had the same error and replaced the dot notation with bracket notation to suppress it.

e.g.: obj.name -> obj['name']

StackOverflow will not allow me to comment on hesselbom's answer (not enough reputation), so I'm adding my own...

$array = preg_split('/\s*\R\s*/', trim($text), NULL, PREG_SPLIT_NO_EMPTY);

This worked best for me because it also eliminates leading (second \s*) and trailing (first \s*) whitespace automatically and also skips blank lines (the PREG_SPLIT_NO_EMPTY flag).

-= OPTIONS =-

If you want to keep leading whitespace, simply get rid of the second \s* and make it an rtrim() instead...

$array = preg_split('/\s*\R/', rtrim($text), NULL, PREG_SPLIT_NO_EMPTY);

If you need to keep empty lines, get rid of the NULL (it is only a placeholder) and PREG_SPLIT_NO_EMPTY flag, like so...

$array = preg_split('/\s*\R\s*/', trim($text));

Or keeping both leading whitespace and empty lines...

$array = preg_split('/\s*\R/', rtrim($text));

I don't see any reason why you'd ever want to keep trailing whitespace, so I suggest leaving the first \s* in there. But, if all you want is to split by new line (as the title suggests), it is THIS simple (as mentioned by Jan Goyvaerts)...

$array = preg_split('/\R/', $text);

For those looking to use axios-mock-adapter in place of the mockfetch example in the Redux documentation for async testing, I successfully used the following:

File actions.test.js:

describe('SignInUser', () => {
  var history = {
    push: function(str) {
        expect(str).toEqual('/feed');
    }
  }

  it('Dispatches authorization', () => {
    let mock = new MockAdapter(axios);
    mock.onPost(`${ROOT_URL}/auth/signin`, {
        email: '[email protected]',
        password: 'test'
    }).reply(200, {token: 'testToken' });

    const expectedActions = [ { type: types.AUTH_USER } ];
    const store = mockStore({ auth: [] });

    return store.dispatch(actions.signInUser({
        email: '[email protected]',
        password: 'test',
      }, history)).then(() => {
        expect(store.getActions()).toEqual(expectedActions);
  });

});

In order to test a successful case for signInUser in file actions/index.js:

export const signInUser = ({ email, password }, history) => async dispatch => {
  const res = await axios.post(`${ROOT_URL}/auth/signin`, { email, password })
    .catch(({ response: { data } }) => {
        ...
  });

  if (res) {
    dispatch({ type: AUTH_USER });                 // Test verified this
    localStorage.setItem('token', res.data.token); // Test mocked this
    history.push('/feed');                         // Test mocked this
  }
}

Given that this is being done with jest, the localstorage call had to be mocked. This was in file src/setupTests.js:

const localStorageMock = {
  removeItem: jest.fn(),
  getItem: jest.fn(),
  setItem: jest.fn(),
  clear: jest.fn()
};
global.localStorage = localStorageMock;

I have not seen any option in Microsoft SQL Server Management Studio 2012 to-date that will do that.

var trElement = tdElement.parentNode;
trElement.removeChild(tdElement);
trElement.innerHTML = str + trElement.innerHTML;

Update Android SDK Tools in Android SDK Manager for revision 22.0.1. It worked for me.

If you go to the Flat file connection manager under Advanced and Look at the "OutputColumnWidth" description's ToolTip It will tell you that Composit characters may use more spaces. So the "é" in "Société" most likely occupies more than one character.

EDIT: Here's something about it: http://en.wikipedia.org/wiki/Precomposed_character

Branches are made of wood and grow from the trunk of the tree. Tags are made of paper (derivative of wood) and hang like Christmas Ornaments from various places in the tree.

Your project is the tree, and your feature that will be added to the project will grow on a branch. The answer is branch.

Use this command to install npm as the sudo user:

sudo npm install -g create-react-app 

instead of npm install -g create-react-a pp.

For mine I did it by setting the div's max width, hence for small widget won't get affected and the large widget is resized due to the max-width style.

  // assuming your widget class is "widget"
  .widget {
    max-width: 100%;
    height: auto;
  }

Say suppose, you have

File f  = new File("SomeFile");
f.length();

You need not close the Files, because its just the representation of a path.

You should always consider to close only reader/writers and in fact streams.

I found this question while googling for a way to auto-format phone numbers via a jQuery plugin. The accepted answer was not ideal for my needs and a lot has happened in the 6 years since it was originally posted. I eventually found the solution and am documenting it here for posterity.

Problem

I would like my phone number html input field to auto-format (mask) the value as the user types.

Solution

Check out Cleave.js. It is a very powerful/flexible and easy way to solve this problem, and many other data masking issues.

Formatting a phone number is as easy as:

var cleave = new Cleave('.input-element', {
    phone: true,
    phoneRegionCode: 'US'
});

The Placeholder does not render any tags for itself, so it is great for grouping content without the overhead of outer HTML tags.

The Panel does have outer HTML tags but does have some cool extra properties.

• BackImageUrl: Gets/Sets the background image's URL for the panel

• HorizontalAlign: Gets/Sets the
  horizontal alignment of the parent's contents

• Wrap: Gets/Sets whether the
  panel's content wraps

There is a good article at startvbnet here.

There is also the strncmp() function and strncasecmp() function which is perfect for this situation:

if (strncmp($string_n, "http", 4) === 0)

In general:

if (strncmp($string_n, $prefix, strlen($prefix)) === 0)

The advantage over the substr() approach is that strncmp() just does what needs to be done, without creating a temporary string.

Have you tried checking the API?

You will need to create a listener for the OnTabSelectedListener event, then when a user selects any tab you should check if it is the correct one, then change the background color using tabLayout.setBackgroundColor(int color), or if it is not the correct tab make sure you change back to the normal color again with the same method.

https://www.w3.org/TR/html5/sec-forms.html#element-attrdef-form-novalidate

You can disable the validation in the form.

A few miscellaneous thoughts on this topic:

1. There is nothing unsafe about any of the hash iterators themselves. What is unsafe is modifying the keys of a hash while you're iterating over it. (It's perfectly safe to modify the values.) The only potential side-effect I can think of is that values returns aliases which means that modifying them will modify the contents of the hash. This is by design but may not be what you want in some circumstances.
2. John's accepted answer is good with one exception: the documentation is clear that it is not safe to add keys while iterating over a hash. It may work for some data sets but will fail for others depending on the hash order.
3. As already noted, it is safe to delete the last key returned by each. This is not true for keys as each is an iterator while keys returns a list.

Multiple where clauses

    $query=DB::table('users')
        ->whereRaw("users.id BETWEEN 1003 AND 1004")
        ->whereNotIn('users.id', [1005,1006,1007])
        ->whereIn('users.id',  [1008,1009,1010]);
    $query->where(function($query2) use ($value)
    {
        $query2->where('user_type', 2)
            ->orWhere('value', $value);
    });

   if ($user == 'admin'){
        $query->where('users.user_name', $user);
    }

finally getting the result

    $result = $query->get();

Localhost is the computer you're using right now. You run things by typing commands at the command prompt and pressing Enter. If you're asking how to run things from your programming environment, then the answer depends on which environment you're using. Most languages have commands with names like system or exec for running external programs. You need to be more specific about what you're actually looking to do, and what obstacles you've encountered while trying to achieve it.

Calling

for /?

in the command-line gives help about this syntax (which can be used outside FOR, too, this is just the place where help can be found).

In addition, substitution of FOR variable references has been enhanced. You can now use the following optional syntax:

%~I         - expands %I removing any surrounding quotes (")
%~fI        - expands %I to a fully qualified path name
%~dI        - expands %I to a drive letter only
%~pI        - expands %I to a path only
%~nI        - expands %I to a file name only
%~xI        - expands %I to a file extension only
%~sI        - expanded path contains short names only
%~aI        - expands %I to file attributes of file
%~tI        - expands %I to date/time of file
%~zI        - expands %I to size of file
%~$PATH:I   - searches the directories listed in the PATH
               environment variable and expands %I to the
               fully qualified name of the first one found.
               If the environment variable name is not
               defined or the file is not found by the
               search, then this modifier expands to the
               empty string

The modifiers can be combined to get compound results:

%~dpI       - expands %I to a drive letter and path only
%~nxI       - expands %I to a file name and extension only
%~fsI       - expands %I to a full path name with short names only
%~dp$PATH:I - searches the directories listed in the PATH
               environment variable for %I and expands to the
               drive letter and path of the first one found.
%~ftzaI     - expands %I to a DIR like output line

In the above examples %I and PATH can be replaced by other valid values. The %~ syntax is terminated by a valid FOR variable name. Picking upper case variable names like %I makes it more readable and avoids confusion with the modifiers, which are not case sensitive.

There are different letters you can use like f for "full path name", d for drive letter, p for path, and they can be combined. %~ is the beginning for each of those sequences and a number I denotes it works on the parameter %I (where %0 is the complete name of the batch file, just like you assumed).

It already exists with find only not in that exact syntax.

if (m.find(2) == m.end() )
{
    // key 2 doesn't exist
}

If you want to access the value if it exists, you can do:

map<int, Bar>::iterator iter = m.find(2);
if (iter != m.end() )
{
    // key 2 exists, do something with iter->second (the value)
}

With C++0x and auto, the syntax is simpler:

auto iter = m.find(2);
if (iter != m.end() )
{
    // key 2 exists, do something with iter->second (the value)
}

I recommend you get used to it rather than trying to come up with a new mechanism to simplify it. You might be able to cut down a little bit of code, but consider the cost of doing that. Now you've introduced a new function that people familiar with C++ won't be able to recognize.

If you want to implement this anyway in spite of these warnings, then:

template <class Key, class Value, class Comparator, class Alloc>
bool getValue(const std::map<Key, Value, Comparator, Alloc>& my_map, int key, Value& out)
{
    typename std::map<Key, Value, Comparator, Alloc>::const_iterator it = my_map.find(key);
    if (it != my_map.end() )
    {
        out = it->second;
        return true;
    }
    return false;
}

From Laravel 5.6 you can use whereDate:

$users = Users::where('status_id', 'active')
       ->whereDate( 'created_at', '>', now()->subDays(30))
       ->get();

You also have whereMonth / whereDay / whereYear / whereTime

For those interested it is easy to change but for a lover of Netbeans and the auto-format you can change the key binding from F12 to ctrl+shift+F to use your beloved key binding. Sad part is that you have to select all to format the entire file. Netbeans still has the upper hand on that. If anyone knows how to overcome that limitation I'm all ears. Otherwise happy reindenting (auto-formating).

All hover is doing behind the scenes is binding to the mouseover and mouseout property. I would bind and unbind your functions from those events individually.

For example, say you have the following html:

<a href="#" class="myLink">Link</a>

then your jQuery would be:

$(document).ready(function() {

  function mouseOver()
  {
    $(this).css('color', 'red');
  }
  function mouseOut()
  {
    $(this).css('color', 'blue');
  }

  // either of these might work
  $('.myLink').hover(mouseOver, mouseOut); 
  $('.myLink').mouseover(mouseOver).mouseout(mouseOut); 
  // otherwise use this
  $('.myLink').bind('mouseover', mouseOver).bind('mouseout', mouseOut);


  // then to unbind
  $('.myLink').click(function(e) {
    e.preventDefault();
    $('.myLink').unbind('mouseover', mouseOver).unbind('mouseout', mouseOut);
  });

});

What I did is simple and straightforward.

Enter Space or \n or whatever you want to find to Find.

Then hit Find All at right bottom corner, this will select all results.

Then hit enter on your keyboard and it will break all selected into new lines.

Consider setState call

this.setState({ counter: this.state.counter + 1 })

IDEA

setState may be called in async function

So you cannot rely on this. If the above call was made inside a async function this will refer to state of component at that point of time but we expected this to refer to property inside state at time setState calling or beginning of async task. And as task was async call thus that property may have changed in time being. Thus it is unreliable to use this keyword to refer to some property of state thus we use callback function whose arguments are previousState and props which means when async task was done and it was time to update state using setState call prevState will refer to state now when setState has not started yet. Ensuring reliability that nextState would not be corrupted.

Wrong Code: would lead to corruption of data

this.setState(
   {counter:this.state.counter+1}
 );

Correct Code with setState having call back function:

 this.setState(
       (prevState,props)=>{
           return {counter:prevState.counter+1};
        }
    );

Thus whenever we need to update our current state to next state based on value possed by property just now and all this is happening in async fashion it is good idea to use setState as callback function.

I have tried to explain it in codepen here CODE PEN

Joda Time

If I am understanding the question correctly, it can be done very easily by using joda time

LocalDate fromDate = new LocalDate().withDayOfMonth(1);
LocalDate toDate = new LocalDate().minusDays(1);

Regarding apply vs map:

pool.apply(f, args): f is only executed in ONE of the workers of the pool. So ONE of the processes in the pool will run f(args).

pool.map(f, iterable): This method chops the iterable into a number of chunks which it submits to the process pool as separate tasks. So you take advantage of all the processes in the pool.

Absolutely - you basically want:

var results = from p in persons
              group p.car by p.PersonId into g
              select new { PersonId = g.Key, Cars = g.ToList() };

Or as a non-query expression:

var results = persons.GroupBy(
    p => p.PersonId, 
    p => p.car,
    (key, g) => new { PersonId = key, Cars = g.ToList() });

Basically the contents of the group (when viewed as an IEnumerable<T>) is a sequence of whatever values were in the projection (p.car in this case) present for the given key.

For more on how GroupBy works, see my Edulinq post on the topic.

(I've renamed PersonID to PersonId in the above, to follow .NET naming conventions.)

Alternatively, you could use a Lookup:

var carsByPersonId = persons.ToLookup(p => p.PersonId, p => p.car);

You can then get the cars for each person very easily:

// This will be an empty sequence for any personId not in the lookup
var carsForPerson = carsByPersonId[personId];

You can use this to continue using the type Date and a more legible code, if you preffer:

import org.apache.commons.lang.time.DateUtils;
...
Date yourDate = DateUtils.addDays(new Date(), *days here*);

In HTML5 there is no scrolling attribute because "its function is better handled by CSS" see http://www.w3.org/TR/html5-diff/ for other changes. Well and the CSS solution:

CSS solution:

HTML4's scrolling="no" is kind of an alias of the CSS's overflow: hidden, to do so it is important to set size attributes width/height:

iframe.noScrolling{
  width: 250px; /*or any other size*/
  height: 300px; /*or any other size*/
  overflow: hidden;
}

Add this class to your iframe and you're done:

<iframe src="http://www.example.com/" class="noScrolling"></iframe>

! IMPORTANT NOTE ! : overflow: hidden for <iframe> is not fully supported by all modern browsers yet(even chrome doesn't support it yet) so for now (2013) it's still better to use Transitional version and use scrolling="no" and overflow:hidden at the same time :)

UPDATE 2020: the above is still true, oveflow for iframes is still not supported by all majors

Put your class name on the mat-form-field element. This works for all inputs.

You can simply access it like an array i.e. v[i] = v[i] - some_num;

Second Thomas David Kehoe, with the following caveat --

If you are using node version manager (nvm), your global node modules will be stored under whatever version of node you are using at the time you saved the module.

So ~/.nvm/versions/node/{version}/lib/node_modules/.

This should work:

DateTime.Now.ToString("hh.mm.ss.ffffff");

If you don't need it to be displayed and just need to know the time difference, well don't convert it to a String. Just leave it as, DateTime.Now();

And use TimeSpan to know the difference between time intervals:

Example

DateTime start;
TimeSpan time;

start = DateTime.Now;

//Do something here

time = DateTime.Now - start;
label1.Text = String.Format("{0}.{1}", time.Seconds, time.Milliseconds.ToString().PadLeft(3, '0'));

Simple solution to emit and show message by Exception.

try {
  throw new TypeError("Error message");
}
catch (e){
  console.log((<Error>e).message);//conversion to Error type
}

Caution

Above is not a solution if we don't know what kind of error can be emitted from the block. In such cases type guards should be used and proper handling for proper error should be done - take a look on @Moriarty answer.

If you use the Eclipse IDE with the SVN plugin you can do as follows:

1. Right-click the files that you want to revert (or the folder they were contained in, if you deleted them by mistake and you want to add them back)
2. Select "Team > Switch"
3. Choose the "Revision" radion button, and enter the revision number you'd like to revert to. Click OK
4. Go to the Synchronize perspective
5. Select all the files you want to revert
6. Right-click on the selection and do "Override and Commit..."

This will revert the files to the revision that you want. Just keep in mind that SVN will see the changes as a new commit. That is, the change gets a new revision number, and there is no link between the old revision and the new one. You should specify in the commit comments that you are reverting those files to a specific revision.

You can also use printf style of formatting arguments. It is available in at least Chrome, Firefox/Firebug and node.js.

var name = prompt("what is your name?");

console.log("story %s story", name);

It also supports %d for formatting numbers

You probably need to do a git stash before you git pull, this is because it is reading your old config file. So do:

git stash
git pull
git commit -am <"say first commit">
git push

Also see git-stash(1) Manual Page.

U can use mysql dump or query to export data to csv file

SELECT *
INTO OUTFILE '/tmp/products.csv'
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
ESCAPED BY '\\'
LINES TERMINATED BY '\n'
FROM products

It's very simple. Suppose that you have made changes to your Branch A which resides on both place locally and remotely but you want to push these changes to Branch B which doesn't exist anywhere.

Step-01: create and switch to the new branch B

git checkout -b B

Step-02: Add changes in the new local branch

git add . //or specific file(s)

Step-03: Commit the changes

git commit -m "commit_message"

Step-04: Push changes to the new branch B. The below command will create a new branch B as well remotely

git push origin B

Now, you can verify from bitbucket that the branch B will have one more commit than branch A. And when you will checkout the branch A these changes won't be there as these have been pushed into the branch B.

Note: If you have commited your changes into the branch A and after that you want to shift those changes into the new branch B then you will have to reset those changes first. #HappyLearning

List indexes of -x mean the xth item from the end of the list, so n[-1] means the last item in the list n. Any good Python tutorial should have told you this.

It's an unusual convention that only a few other languages besides Python have adopted, but it is extraordinarily useful; in any other language you'll spend a lot of time writing n[n.length-1] to access the last item of a list.

In all versions of MySQL, simply alias the aggregate in the SELECT list, and order by the alias:

SELECT COUNT(id) AS theCount, `Tag` from `images-tags`
GROUP BY `Tag`
ORDER BY theCount DESC
LIMIT 20

This worked for me

    static DateToYYYYMMDD(Date: Date): string {
        let DS: string = Date.getFullYear()

            + '/' + ('0' + Date.getDate()).slice(-2)
        return DS
    }

You can certainly add HH:MM something like this...

    static DateToYYYYMMDD_HHMM(Date: Date): string {
        let DS: string = Date.getFullYear()
            + '/' + ('0' + (Date.getMonth() + 1)).slice(-2)
            + '/' + ('0' + Date.getDate()).slice(-2)
            + ' ' + ('0' + Date.getHours()).slice(-2)
            + ':' + ('0' + Date.getMinutes()).slice(-2)
        return DS
    }

I faced the same issue. But i resolved it by changing my port numbers to different one.

My approach:

• define a default constraint on the ModDate column with a value of GETDATE() - this handles the INSERT case

• have a AFTER UPDATE trigger to update the ModDate column

Something like:

CREATE TRIGGER trg_UpdateTimeEntry
ON dbo.TimeEntry
AFTER UPDATE
AS
    UPDATE dbo.TimeEntry
    SET ModDate = GETDATE()
    WHERE ID IN (SELECT DISTINCT ID FROM Inserted)

We can use the JSONObject class to convert a JSON string to a JSON object, and to iterate over the JSON object. Use the following code.

JSONObject jObj = new JSONObject(contents.trim());
Iterator<?> keys = jObj.keys();

while( keys.hasNext() ) {
  String key = (String)keys.next();
  if ( jObj.get(key) instanceof JSONObject ) {           
    System.out.println(jObj.getString(String key));
  }
}

The second result set have only one column but it should have 3 columns for it to be contented to the first result set

(columns must match when you use UNION)

Try to add ID as first column and PartOf_LOC_id to your result set, so you can do the UNION.

;
WITH    q AS ( SELECT   ID ,
                    Location ,
                    PartOf_LOC_id
           FROM     tblLocation t
           WHERE    t.ID = 1 -- 1 represents an example
           UNION ALL
           SELECT   t.ID ,
                    parent.Location + '>' + t.Location ,
                    t.PartOf_LOC_id
           FROM     tblLocation t
                    INNER JOIN q parent ON parent.ID = t.LOC_PartOf_ID
         )
SELECT  *
FROM    q

You must set the settings in the file 'Startup.cs'

You also have to define it in the default values of JsonConvert, this is if you later want to directly use the library to serialize an object.

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2)
            .AddJsonOptions(options => {
                options.SerializerSettings.NullValueHandling = NullValueHandling.Ignore;
                options.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
            });
        JsonConvert.DefaultSettings = () => new JsonSerializerSettings
        {
            NullValueHandling = NullValueHandling.Ignore,
            ContractResolver = new CamelCasePropertyNamesContractResolver()
        };
    }

Ok you can use this simply

-webkit-text-stroke-width: .7px;
-webkit-text-stroke-color: #34343b;
-webkit-font-smoothing:antialiased;

Make sure your text color and upper text-stroke-width must me same and that's it.

There was an issue with a build of Google Chrome Dev build 24.0.1312.5 that caused the preview panel to no longer display a json object tree but rather flat text. It should be fixed in the next dev

The answer depends on the presence of other shapes, level of noise if any and invariance you want to provide for (e.g. rotation, scaling, etc). These requirements will define not only the algorithm but also required pre-procesing stages to extract features.

Template matching that was suggested above works well when shapes aren't rotated or scaled and when there are no similar shapes around; in other words, it finds a best translation in the image where template is located:

double minVal, maxVal;
Point minLoc, maxLoc;
Mat image, template, result; // template is your shape
matchTemplate(image, template, result, CV_TM_CCOEFF_NORMED);
minMaxLoc(result, &minVal, &maxVal, &minLoc, &maxLoc); // maxLoc is answer

Geometric hashing is a good method to get invariance in terms of rotation and scaling; this method would require extraction of some contour points.

Generalized Hough transform can take care of invariance, noise and would have minimal pre-processing but it is a bit harder to implement than other methods. OpenCV has such transforms for lines and circles.

In the case when number of shapes is limited calculating moments or counting convex hull vertices may be the easiest solution: openCV structural analysis

Check to make sure there is a film release date; if the date is missing you will not be able to format on a non-object.

if ($info['Film_Release']){ //check if the date exists
   $dateFromDB = $info['Film_Release'];
   $newDate = DateTime::createFromFormat("l dS F Y", $dateFromDB);
   $newDate = $newDate->format('d/m/Y'); 
} else {
   $newDate = "none"; 
}

or

 $newDate = ($info['Film_Release']) ? DateTime::createFromFormat("l dS F Y", $info['Film_Release'])->format('d/m/Y'): "none" 

If it is a c-string (null-terminated array of type char), you can do something like:

#include <stdlib.h>
char str[] = "3.14159";
double num = atof(str);

If it is a C++ string, just use the c_str() method:

double num = atof( cppstr.c_str() );

atof() will convert the string to a double, returning 0 on failure. The function is documented here: http://www.cplusplus.com/reference/clibrary/cstdlib/atof.html

Here it is how to use MockHttpServletRequest:

// given
MockHttpServletRequest request = new MockHttpServletRequest();
request.setServerName("www.example.com");
request.setRequestURI("/foo");
request.setQueryString("param1=value1&param");

// when
String url = request.getRequestURL() + '?' + request.getQueryString(); // assuming there is always queryString.

// then
assertThat(url, is("http://www.example.com:80/foo?param1=value1&param"));

In order to delete the 'native' node.js installation, I have used the method suggested in previous answers sudo npm uninstall npm -g, with additional sudo rm -rf /usr/local/lib/node /usr/local/lib/node_modules /var/db/receipts/org.nodejs.*.

BUT, I had to also delete the following two directories:

sudo rm -rf /usr/local/include/node /Users/$USER/.npm

Only after that I could install node.js with Homebrew.

If you don't want to make the button a separate image, you can use the <area> tag. This is done by using html similar to this:

<img src="imgsrc" width="imgwidth" height="imgheight" alt="alttext" usemap="#mapname">

<map name="mapname">
    <area shape="rect" coords="see note 1" href="link" alt="alttext">
</map>

Note 1: The coords=" " attribute must be formatted in this way: coords="x1,y1,x2,y2" where:

x1=top left X coordinate
y1=top left Y coordinate
x2=bottom right X coordinate
y2=bottom right Y coordinate

Note 2: The usemap="#mapname" attribute must include the #.

EDIT:

I looked at your code and added in the <map> and <area> tags where they should be. I also commented out some parts that were either overlapping the image or seemed there for no use.

</ul> -->

Notes:

1. The coord="48,341,294,275" is in reference to your screenshot you posted.
2. The src="./test.png" is the location and name of the screenshot you posted on my computer.
3. The href="http://www.example.com/" is an example link.

You can use Case expression for returning a boolean in your select query like below.

        mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
        mapper.configure(MapperFeature.DEFAULT_VIEW_INCLUSION, true);

        return mapper;
    }

Fixed this issue by concatenating my certificates to generate a valid certificate chain (using GoDaddy Standard SSL + Nginx).

http://nginx.org/en/docs/http/configuring_https_servers.html#chains

To generate the chain:

cat 123456789.crt gd_bundle-g2-g1.crt > my.domain.com.chained.crt

Then:

ssl_certificate /etc/nginx/ssl/my.domain.com.chained.crt;
ssl_certificate_key /etc/nginx/ssl/my.domain.com.key;

Hope it helps!

Double check that you're referencing the correct type from the ServiceHost directive in the .svc file. Here's how...

1. In the VS project containing your web service, open the .svc file in the XML editor (right-click the file, Open With..., choose XML (Text) Editor, OK).
2. Note the "Service" attribute value.
3. Make sure it matches the fully qualified type name of your service. This includes the namespace + type name. For example, if the namespace is "MyCompany.Department.Services" and the class is called "MyService", then the Service attribute value should be "MyCompany.Department.Services.MyService".

If you only need to compare two files, I guess the fastest way would be (in C, I don't know if it's applicable to .NET)

1. open both files f1, f2
2. get the respective file length l1, l2
3. if l1 != l2 the files are different; stop
4. mmap() both files
5. use memcmp() on the mmap()ed files

OTOH, if you need to find if there are duplicate files in a set of N files, then the fastest way is undoubtedly using a hash to avoid N-way bit-by-bit comparisons.

In this case no conditionals are needed to set the variable.

This one-liner XPath expression:

boolean(joined-subclass)

is true() only when the child of the current node, named joined-subclass exists and it is false() otherwise.

The complete stylesheet is:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes"/>

 <xsl:template match="class">
   <xsl:variable name="subexists"
        select="boolean(joined-subclass)"
   />

   subexists:  <xsl:text/>
   <xsl:value-of select="$subexists" />
 </xsl:template>
</xsl:stylesheet>

Do note, that the use of the XPath function boolean() in this expression is to convert a node (or its absense) to one of the boolean values true() or false().

Change the stdout from the rsync process to be unbuffered.

                     stdout=subprocess.PIPE)

You should have a look at numpy if you do matrix manipulation. This is a module mainly written in C, which will be much faster than programming in pure python. Here is an example of how to invert a matrix, and do other matrix manipulation.

from numpy import matrix
from numpy import linalg
A = matrix( [[1,2,3],[11,12,13],[21,22,23]]) # Creates a matrix.
x = matrix( [[1],[2],[3]] )                  # Creates a matrix (like a column vector).
y = matrix( [[1,2,3]] )                      # Creates a matrix (like a row vector).
print A.T                                    # Transpose of A.
print A*x                                    # Matrix multiplication of A and x.
print A.I                                    # Inverse of A.
print linalg.solve(A, x)     # Solve the linear equation system.

You can also have a look at the array module, which is a much more efficient implementation of lists when you have to deal with only one data type.

#progressbar {_x000D_
  background-color: black;_x000D_
  border-radius: 13px;_x000D_

(EDIT: Changed Syntax highlight; changed descendant to child selector)

A quick wrap up. Maybe someone has a better explanation.

A call stack is composed of 1 or many several stack frames. Each stack frame corresponds to a call to a function or procedure which has not yet terminated with a return.

To use a stack frame, a thread keeps two pointers, one is called the Stack Pointer (SP), and the other is called the Frame Pointer (FP). SP always points to the "top" of the stack, and FP always points to the "top" of the frame. Additionally, the thread also maintains a program counter (PC) which points to the next instruction to be executed.

The following are stored on the stack: local variables and temporaries, actual parameters of the current instruction (procedure, function, etc.)

There are different calling conventions regarding the cleaning of the stack.

Alright, so I ended up going with the code I wrote here, on my website ^{link is dead, view on archive.org} (also available on GitHub). I can use it in the following fashion:

from filelock import FileLock

with FileLock("myfile.txt.lock"):
    print("Lock acquired.")
    with open("myfile.txt"):
        # work with the file as it is now locked

Here is a fairly simple way to get the args and set them as env vars. In this example I will just refer to them as Keys and Values.

Save the following code example as "args.bat". Then call the batch file you saved from a command line. example: arg.bat --x 90 --y 120

I have provided some echo commands to step you through the process. But the end result is that --x will have a value of 90 and --y will have a value of 120(that is if you run the example as specified above ;-) ).

You can then use the 'if defined' conditional statement to determine whether or not to run your code block. So lets say run: "arg.bat --x hello-world" I could then use the statement "IF DEFINED --x echo %--x%" and the results would be "hello-world". It should make more sense if you run the batch.

I was facing the same error, and look what I was doing. My bad, I was trying to add the same view NativeAdView to the multiple FrameLayouts, resolved by creating a separate view NativeAdView for each FrameLayout, Thanks

I think for readability and speed @oxrock's solution is the best, so here is the code rewritten for python 3+:

def num_factors(n):
    results = set()
    for i in range(1, int(n**0.5) + 1):
        if n % i == 0: results.update([i,int(n/i)])
    return results

As stated in this blog post it seems possible to use mod_security to implement a rate limit per second.

The configuration is something like this:

SecRuleEngine On

<LocationMatch "^/somepath">
  SecAction initcol:ip=%{REMOTE_ADDR},pass,nolog
  SecAction "phase:5,deprecatevar:ip.somepathcounter=1/1,pass,nolog"
  SecRule IP:SOMEPATHCOUNTER "@gt 60" "phase:2,pause:300,deny,status:509,setenv:RATELIMITED,skip:1,nolog"
  SecAction "phase:2,pass,setvar:ip.somepathcounter=+1,nolog"
  Header always set Retry-After "10" env=RATELIMITED
</LocationMatch>

ErrorDocument 509 "Rate Limit Exceeded"

Well in my case, I just rename the Bundle Name and Executable file values in info.plist same as project name. It worked for me.

Keep it Simple!

Simpler and a Standard solution to increment the number and to retain the dot at the end. Even if you get the css right, it will not work if your HTML is not correct. see below.

CSS

ol {
  counter-reset: item;
}
ol li {
  display: block;
}
ol li:before {
  content: counters(item, ". ") ". ";
  counter-increment: item;
}

SASS

ol {
    counter-reset: item;
    li {
        display: block;
        &:before {
            content: counters(item, ". ") ". ";
            counter-increment: item
        }
    }
}

HTML Parent Child

If you add the child make sure the it is under the parent li.

<!-- WRONG -->
<ol>
    <li>Parent 1</li> <!-- Parent is Individual. Not hugging -->
        <ol> 
            <li>Child</li>
        </ol>
    <li>Parent 2</li>
</ol>

<!-- RIGHT -->
<ol>
    <li>Parent 1 
        <ol> 
            <li>Child</li>
        </ol>
    </li> <!-- Parent is Hugging the child -->
    <li>Parent 2</li>
</ol>

To consider multiple column.

Sort and give unique list based on column 1 and column 3:

sort -u -t : -k 1,1 -k 3,3 test.txt

• -t : colon is separator
• -k 1,1 -k 3,3 based on column 1 and column 3

How about this one?

We simply use a try-catch block.

$dateTime = 'an invalid datetime';

try {
    $dateTimeObject = new DateTime($dateTime);
} catch (Exception $exc) {
    echo 'Do something with an invalid DateTime';
}

This approach is not limited to only one date/time format, and you don't need to define any function.

As I found the default Bootstrap <hr/> size unsightly, here's some simple HTML and CSS to balance out the element visually:

HTML:

<hr class="half-rule"/>

CSS:

.half-rule { 
    margin-left: 0;
    text-align: left;
    width: 50%;
 }

Check out DecimalFormat: http://docs.oracle.com/javase/6/docs/api/java/text/DecimalFormat.html

You'll do something like:

new DecimalFormat("$#.00").format(shippingCost);

Or since you're working with currency, you could see how NumberFormat.getCurrencyInstance() works for you.

Summary:

The new keyword is used in javascript to create a object from a constructor function. The new keyword has to be placed before the constructor function call and will do the following things:

1. Creates a new object
2. Sets the prototype of this object to the constructor function's prototype property
3. Binds the this keyword to the newly created object and executes the constructor function
4. Returns the newly created object

Example:

function Dog (age) {
  this.age = age;
}

const doggie = new Dog(12);

console.log(doggie);
console.log(Object.getPrototypeOf(doggie) === Dog.prototype) // true

What exactly happens:

1. const doggie says: We need memory for declaring a variable.
2. The assigment operator = says: We are going to initialize this variable with the expression after the =
3. The expression is new Dog(12). The JS engine sees the new keyword, creates a new object and sets the prototype to Dog.prototype
4. The constructor function is executed with the this value set to the new object. In this step is where the age is assigned to the new created doggie object.
5. The newly created object is returned and assigned to the variable doggie.

Above answers didn't work for me. I used filter-branch to remove all committed files.

Remove a file from a git repository with:

git filter-branch --tree-filter 'rm  file'

Remove a folder from a git repository with:

git filter-branch --tree-filter 'rm -rf directory'

This removes the directory or file from all the commits.

You can specify a commit by using:

git filter-branch --tree-filter 'rm -rf directory' HEAD

Or an range:

git filter-branch --tree-filter 'rm -rf vendor/gems' t49dse..HEAD

To push everything to remote, you can do:

git push origin master --force

Sounds like a job for VLOOKUP!

You can put your 32 -> 1420 type mappings in a couple of columns somewhere, then use the VLOOKUP function to perform the lookup.

WARNING:

Going for a 'git pull' is not ALWAYS a solution, so be carefull. You may face this problem (the one that is mentioned in the Q) if you have intentionally changed your repository history. In that case, git is confusing your history changes with new changes in your remote repo. So, you should go for a git push --force, because calling git pull will undo all of the changes you made to your history, intentionally.

private SelectList AddFirstItem(SelectList list)
        {
            List<SelectListItem> _list = list.ToList();
            _list.Insert(0, new SelectListItem() { Value = "-1", Text = "This Is First Item" });
            return new SelectList((IEnumerable<SelectListItem>)_list, "Value", "Text");
        }

This Should do what you need ,just send your selectlist and it will return a select list with an item in index 0

You can custome the text,value or even the index of the item you need to insert

Function Pointers can have very different sizes, from 4 to 20 Bytes on an X86 machine, depending on the compiler. So the answer is NO - sizes can vary.

Another example: take an 8051 program, it has three memory ranges and thus has three different pointer sizes, from 8 bit, 16bit, 24bit, depending on where the target is located, even though the target's size is always the same (e.g. char).

When you write an implementation file (.cpp, .cxx, etc) your compiler generates a translation unit. This is the source file from your implementation plus all the headers you #included in it.

Internal linkage refers to everything only in scope of a translation unit.

External linkage refers to things that exist beyond a particular translation unit. In other words, accessible through the whole program, which is the combination of all translation units (or object files).

When you add dependency in pom.xml , do a maven clean , and then maven build , it will add the jars into you project.

You can search dependency artifacts at http://mvnrepository.com/

And if it doesn't add jars it should give you errors which will mean that it is not able to fetch the jar, that could be due to broken repository or connection problems.

Well sometimes if it is one or two jars, better download them and add to build path , but with a lot of dependencies use maven.

Since July 2017 you can use cmp.Equal with cmpopts.IgnoreFields option.

func TestPerson(t *testing.T) {
    type person struct {
        ID   int
        Name string
    }

    p1 := person{ID: 1, Name: "john doe"}
    p2 := person{ID: 2, Name: "john doe"}
    println(cmp.Equal(p1, p2))
    println(cmp.Equal(p1, p2, cmpopts.IgnoreFields(person{}, "ID")))

    // Prints:
    // false
    // true
}

Wanted to add numexpr into the mix:

import numpy as np
import numexpr as ne

a = np.array([1, 3, 5, 6, 9, 10, 14, 15, 56])  

np.where(ne.evaluate("(6 <= a) & (a <= 10)"))[0]
# array([3, 4, 5], dtype=int64)

Would only make sense for larger arrays with millions... or if you hitting a memory limits.

There is no notion of method overloading in Python. But you can achieve a similar effect by specifying optional and keyword arguments

In Python >=3.2, that's

os.makedirs(path, exist_ok=True)

In earlier versions, use @tzot's answer.

Could you try this out?

=IIF((Fields!OpeningStock.Value=0) AND (Fields!GrossDispatched.Value=0) AND 
(Fields!TransferOutToMW.Value=0) AND (Fields!TransferOutToDW.Value=0) AND 
(Fields!TransferOutToOW.Value=0) AND (Fields!NetDispatched.Value=0) AND (Fields!QtySold.Value=0) 
AND (Fields!StockAdjustment.Value=0) AND (Fields!ClosingStock.Value=0),True,False)

Note: Setting Hidden to False will make the row visible

To mark as obsolete with a warning:

[Obsolete]
private static void SomeMethod()

You get a warning when you use it:

And with IntelliSense:

If you want a message:

[Obsolete("My message")]
private static void SomeMethod()

Here's the IntelliSense tool tip:

Finally if you want the usage to be flagged as an error:

[Obsolete("My message", true)]
private static void SomeMethod()

When used this is what you get:

Note: Use the message to tell people what they should use instead, not why it is obsolete.

I've been wondering if there was a simple way to download a file in a more ... "generic" way. I came up with this.

It's a simple ActionResult that will allow you to download a file from a controller call that returns an IHttpActionResult. The file is stored in the byte[] Content. You can turn it into a stream if needs be.

I used this to return files stored in a database's varbinary column.

    public class FileHttpActionResult : IHttpActionResult
    {
        public HttpRequestMessage Request { get; set; }

        public string FileName { get; set; }
        public string MediaType { get; set; }
        public HttpStatusCode StatusCode { get; set; }

        public byte[] Content { get; set; }

        public Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken)
        {
            HttpResponseMessage response = new HttpResponseMessage(StatusCode);

            response.StatusCode = StatusCode;
            response.Content = new StreamContent(new MemoryStream(Content));
            response.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment");
            response.Content.Headers.ContentDisposition.FileName = FileName;
            response.Content.Headers.ContentType = new MediaTypeHeaderValue(MediaType);

            return Task.FromResult(response);
        }
    }

ProgressDialog has become deprecated since API Level 26 https://developer.android.com/reference/android/app/ProgressDialog.html

I include a ProgressBar in my layout

   <ProgressBar
        android:layout_weight="1"
        android:id="@+id/progressBar_cyclic"
        android:visibility="gone"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:minHeight="40dp"
        android:minWidth="40dp" />

and change its visibility to .GONE | .VISIBLE depending on the use case.

    progressBar_cyclic.visibility = View.VISIBLE

The difference between different date/time formats in ActiveRecord has little to do with Rails and everything to do with whatever database you're using.

Using MySQL as an example (if for no other reason because it's most popular), you have DATE, DATETIME, TIME and TIMESTAMP column data types; just as you have CHAR, VARCHAR, FLOAT and INTEGER.

So, you ask, what's the difference? Well, some of them are self-explanatory. DATE only stores a date, TIME only stores a time of day, while DATETIME stores both.

The difference between DATETIME and TIMESTAMP is a bit more subtle: DATETIME is formatted as YYYY-MM-DD HH:MM:SS. Valid ranges go from the year 1000 to the year 9999 (and everything in between. While TIMESTAMP looks similar when you fetch it from the database, it's really a just a front for a unix timestamp. Its valid range goes from 1970 to 2038. The difference here, aside from the various built-in functions within the database engine, is storage space. Because DATETIME stores every digit in the year, month day, hour, minute and second, it uses up a total of 8 bytes. As TIMESTAMP only stores the number of seconds since 1970-01-01, it uses 4 bytes.

You can read more about the differences between time formats in MySQL here.

In the end, it comes down to what you need your date/time column to do. Do you need to store dates and times before 1970 or after 2038? Use DATETIME. Do you need to worry about database size and you're within that timerange? Use TIMESTAMP. Do you only need to store a date? Use DATE. Do you only need to store a time? Use TIME.

Having said all of this, Rails actually makes some of these decisions for you. Both :timestamp and :datetime will default to DATETIME, while :date and :time corresponds to DATE and TIME, respectively.

This means that within Rails, you only have to decide whether you need to store date, time or both.

ArrayList get(int index) method is used for fetching an element from the list. We need to specify the index while calling get method and it returns the value present at the specified index.

public Element get(int index)

Example : In below example we are getting few elements of an arraylist by using get method.

package beginnersbook.com;
import java.util.ArrayList;
public class GetMethodExample {
   public static void main(String[] args) {
       ArrayList<String> al = new ArrayList<String>();
       al.add("pen");
       al.add("pencil");
       al.add("ink");
       al.add("notebook");
       al.add("book");
       al.add("books");
       al.add("paper");
       al.add("white board");

       System.out.println("First element of the ArrayList: "+al.get(0));
       System.out.println("Third element of the ArrayList: "+al.get(2));
       System.out.println("Sixth element of the ArrayList: "+al.get(5));
       System.out.println("Fourth element of the ArrayList: "+al.get(3));
   }
}

Output:

First element of the ArrayList: pen
Third element of the ArrayList: ink
Sixth element of the ArrayList: books
Fourth element of the ArrayList: notebook

If you want to look for all commits by filename and not by filepath, use:

git log --all -- '*.wmv'

Be careful to type exactly :wq as Wouter Verleur said at step 7. After type enter, you will save the changes and exit the visudo editor to bash.

It's shorter version :

function getDirContents($path) {
    $rii = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path));

    $files = array(); 
    foreach ($rii as $file)
        if (!$file->isDir())
            $files[] = $file->getPathname();

    return $files;
}

var_dump(getDirContents($path));

I had the same problem and tried all of the mentioned solutions to no avail. through testing i found that making the text selectable was preventing the listener to be called. So by switching it to false, or removing it my listener was called again.

android:textIsSelectable="false"

hope this helps someone who was stuck like me.

here is another function to format xml

function formatXml(xml){
    var out = "";
    var tab = "    ";
    var indent = 0;
    var inClosingTag=false;
    var dent=function(no){
        out += "\n";
        for(var i=0; i < no; i++)
            out+=tab;
    }


    for (var i=0; i < xml.length; i++) {
        var c = xml.charAt(i);
        if(c=='<'){
            // handle </
            if(xml.charAt(i+1) == '/'){
                inClosingTag = true;
                dent(--indent);
            }
            out+=c;
        }else if(c=='>'){
            out+=c;
            // handle />
            if(xml.charAt(i-1) == '/'){
                out+="\n";
                //dent(--indent)
            }else{
              if(!inClosingTag)
                dent(++indent);
              else{
                out+="\n";
                inClosingTag=false;
              }
            }
        }else{
          out+=c;
        }
    }
    return out;
}

If the variance of the input is statistically distributed (e.g. normal, log-normal, etc.) then reservoir sampling is a reasonable way of estimating percentiles/medians from an arbitrarily long stream of numbers.

int n = 0;  // Running count of elements observed so far  
#define SIZE 10000
int reservoir[SIZE];  

while(streamHasData())
{
  int x = readNumberFromStream();

  if (n < SIZE)
  {
       reservoir[n++] = x;
  }         
  else 
  {
      int p = random(++n); // Choose a random number 0 >= p < n
      if (p < SIZE)
      {
           reservoir[p] = x;
      }
  }
}

"reservoir" is then a running, uniform (fair), sample of all input - regardless of size. Finding the median (or any percentile) is then a straight-forward matter of sorting the reservoir and polling the interesting point.

Since the reservoir is fixed size, the sort can be considered to be effectively O(1) - and this method runs with both constant time and memory consumption.

Actually there is. There is a static method valueOf in the java.sql.Date object which does exactly that. So we have

java.util.Date date = java.sql.Date.valueOf(localDate);

and that's it. No explicit setting of time zones because the local time zone is taken implicitly.

From docs:

The provided LocalDate is interpreted as the local date in the local time zone.

The java.sql.Date subclasses java.util.Date so the result is a java.util.Date also.

And for the reverse operation there is a toLocalDate method in the java.sql.Date class. So we have:

LocalDate ld = new java.sql.Date(date.getTime()).toLocalDate();

I had similar problem... solved by adding ob_start(); and ob_end_flush(); ...

<?php 
ob_start();


require 'engine/vishnuHTML.class.php';
require 'engine/admin/login.class.php';

$html=new vishnuHTML();
 (!isset($_SESSION))?session_start():"";

/* blah bla Code
...........
...........
 */

</div>
</div>
<?php
}



ob_end_flush();
?>

Think of ob_start() as saying "Start remembering everything that would normally be outputted, but don't quite do anything with it yet."

ob_end_clean() or ob_flush(), which either stops saving things and discards whatever was saved, or stops saving and outputs it all at once, respectively.

First you need to import svg files by following simple steps.

1. Right click on drawable
2. Click new
3. Select Vector Asset

If image is available in your computer then select local svg file. After that select the image path and an option to change the size of the image is also available at the right side of dialog if you want to . in this way svg image is imported in your project After that for using this image use the same procedure

Removing Python 3 was the worst thing I did since I recently moved to the world of Linux. It removed Firefox, my launcher and, as I read while trying to fix my problem, it may also remove your desktop and terminal! Finally fixed after a long daytime nightmare. Just don't remove Python 3. Keep it there!

If that happens to you, here is the fix:

https://askubuntu.com/q/384033/402539

https://askubuntu.com/q/810854/402539

The answer is on the MSDN site:

The Save (Not Permitted) dialog box warns you that saving changes is not permitted because the changes you have made require the listed tables to be dropped and re-created.

The following actions might require a table to be re-created:

• Adding a new column to the middle of the table
• Dropping a column
• Changing column nullability
• Changing the order of the columns
• Changing the data type of a column

EDIT 1:

Additional useful informations from here:

To change the Prevent saving changes that require the table re-creation option, follow these steps:

1. Open SQL Server Management Studio (SSMS).
2. On the Tools menu, click Options.
3. In the navigation pane of the Options window, click Designers.
4. Select or clear the Prevent saving changes that require the table re-creation check box, and then click OK.

Note If you disable this option, you are not warned when you save the table that the changes that you made have changed the metadata structure of the table. In this case, data loss may occur when you save the table.

Risk of turning off the "Prevent saving changes that require table re-creation" option

Although turning off this option can help you avoid re-creating a table, it can also lead to changes being lost. For example, suppose that you enable the Change Tracking feature in SQL Server 2008 to track changes to the table. When you perform an operation that causes the table to be re-created, you receive the error message that is mentioned in the "Symptoms" section. However, if you turn off this option, the existing change tracking information is deleted when the table is re-created. Therefore, we recommend that you do not work around this problem by turning off the option.

The linefeed character \n is not the line separator in certain operating systems (such as windows, where it's "\r\n") - my suggestion is that you use \r\n instead, then it'll both see the line-break with only \n and \r\n, I've never had any problems using it.

Also, you should look into using a StringBuilder instead of concatenating the String in the while-loop at BookCatalog.toString(), it is a lot more effective. For instance:

public String toString() {
        BookNode current = front;
        StringBuilder sb = new StringBuilder();
        while (current!=null){
            sb.append(current.getData().toString()+"\r\n ");
            current = current.getNext();
        }
        return sb.toString();
}

The structs testing.T and testing.B both have a .Log and .Logf method that sound to be what you are looking for. .Log and .Logf are similar to fmt.Print and fmt.Printf respectively.

See more details here: http://golang.org/pkg/testing/#pkg-index

fmt.X print statements do work inside tests, but you will find their output is probably not on screen where you expect to find it and, hence, why you should use the logging methods in testing.

If, as in your case, you want to see the logs for tests that are not failing, you have to provide go test the -v flag (v for verbosity). More details on testing flags can be found here: https://golang.org/cmd/go/#hdr-Testing_flags

$ git config --get-regexp alias

The internals of the GUI system call that method, and they pass in the Graphics parameter as a graphics context onto which you can draw.

1. return None or return can be used to exit out of a function or program, both does the same thing
2. quit() function can be used, although use of this function is discouraged for making real world applications and should be used only in interpreter.

    import site
    
    def func():
        print("Hi")
        quit()
        print("Bye")

3. exit() function can be used, similar to quit() but the use is discouraged for making real world applications.

import site
    
    def func():
        print("Hi")
        exit()
        print("Bye")

4. sys.exit([arg]) function can be used and need to import sys module for that, this function can be used for real world applications unlike the other two functions.

import sys 
  height = 150
  
if height < 165: # in cm 
      
    # exits the program 
    sys.exit("Height less than 165")     
else: 
    print("You ride the rollercoaster.") 

5. os._exit(n) function can be used to exit from a process, and need to import os module for that.

Just expanding Jeroen's answer with the tips in comments:

var content = new StringContent(
    JsonConvert.SerializeObject(user), 
    Encoding.UTF8, 
    MediaTypeNames.Application.Json);

var response = await client.PostAsync("api/AgentCollection", content);

A bin is range that represents the width of a single bar of the histogram along the X-axis. You could also call this the interval. (Wikipedia defines them more formally as "disjoint categories".)

The Numpy histogram function doesn't draw the histogram, but it computes the occurrences of input data that fall within each bin, which in turns determines the area (not necessarily the height if the bins aren't of equal width) of each bar.

In this example:

 np.histogram([1, 2, 1], bins=[0, 1, 2, 3])

There are 3 bins, for values ranging from 0 to 1 (excl 1.), 1 to 2 (excl. 2) and 2 to 3 (incl. 3), respectively. The way Numpy defines these bins if by giving a list of delimiters ([0, 1, 2, 3]) in this example, although it also returns the bins in the results, since it can choose them automatically from the input, if none are specified. If bins=5, for example, it will use 5 bins of equal width spread between the minimum input value and the maximum input value.

The input values are 1, 2 and 1. Therefore, bin "1 to 2" contains two occurrences (the two 1 values), and bin "2 to 3" contains one occurrence (the 2). These results are in the first item in the returned tuple: array([0, 2, 1]).

Since the bins here are of equal width, you can use the number of occurrences for the height of each bar. When drawn, you would have:

• a bar of height 0 for range/bin [0,1] on the X-axis,
• a bar of height 2 for range/bin [1,2],
• a bar of height 1 for range/bin [2,3].

You can plot this directly with Matplotlib (its hist function also returns the bins and the values):

>>> import matplotlib.pyplot as plt
>>> plt.hist([1, 2, 1], bins=[0, 1, 2, 3])
(array([0, 2, 1]), array([0, 1, 2, 3]), <a list of 3 Patch objects>)
>>> plt.show()

From the docs:

The SimpleHTTPServer module has been merged into http.server in Python 3.0. The 2to3 tool will automatically adapt imports when converting your sources to 3.0.

So, your command is python -m http.server, or depending on your installation, it can be:

python3 -m http.server

As far as I know, it's not possible in IE because it uses the OS component.

<select> Something New, Part 1

By Aaron Gustafson

So you've built a beautiful, standards-compliant site utilizing the latest and greatest CSS techniques. You've mastered control of styling every element, but in the back of your mind, a little voice is nagging you about how ugly your <select>s are. Well, today we're going to explore a way to silence that little voice and truly complete our designs. With a little DOM scripting and some creative CSS, you too can make your <select>s beautiful… and you won't have to sacrifice accessibility, usability or graceful degradation.

The Problem

We all know the <select> is just plain ugly. In fact, many try to limit its use to avoid its classic web circa 1994 inset borders. We should not avoid using the <select> though--it is an important part of the current form toolset; we should embrace it. That said, some creative thinking can improve it.

The <select>

We'll use a simple for our example:

<select id="something" name="something">
  <option value="1">This is option 1</option>
  <option value="2">This is option 2</option>
  <option value="3">This is option 3</option>
  <option value="4">This is option 4</option>
  <option value="5">This is option 5</option>
</select>

[Note: It is implied that this <select> is in the context of a complete form.]

So we have five <option>s within a <select>. This <select> has a uniquely assigned id of "something." Depending on the browser/platform you're viewing it on, your <select> likely looks roughly like this:

_{(source: easy-designs.net)}

or this

_{(source: easy-designs.net)}

Let's say we want to make it look a little more modern, perhaps like this:

_{(source: easy-designs.net)}

So how do we do it? Keeping the basic <select> is not an option. Apart from basic background color, font and color adjustments, you don't really have a lot of control over the .

However, we can mimic the superb functionality of a <select> in a new form control without sacrificing semantics, usability or accessibility. In order to do that, we need to examine the nature of a <select>.

A <select> is, essentially, an unordered list of choices in which you can choose a single value to submit along with the rest of a form. So, in essence, it's a <ul> on steroids. Continuing with that line of thinking, we can replace the <select> with an unordered list, as long as we give it some enhanced functionality. As <ul>s can be styled in a myriad of different ways, we're almost home free. Now the questions becomes "how to ensure that we maintain the functionality of the <select> when using a <ul>?" In other words, how do we submit the correct value along with the form, if we are no longer using a form control?

The solution

Enter the DOM. The final step in the process is making the <ul> function/feel like a <select>, and we can accomplish that with JavaScript/ECMA Script and a little clever CSS. Here is the basic list of requirements we need to have a functional faux <select>:

• click the list to open it,
• click on list items to change the value assigned & close the list,
• show the default value when nothing is selected, and
• show the chosen list item when something is selected.

With this plan, we can begin to tackle each part in succession.

Building the list

So first we need to collect all of the attributes and s out of the and rebuild it as a . We accomplish this by running the following JS:

function selectReplacement(obj) {
  var ul = document.createElement('ul');
  ul.className = 'selectReplacement';
  // collect our object's options
  var opts = obj.options;
  // iterate through them, creating <li>s
  for (var i=0; i<opts.length; i++) {
    var li = document.createElement('li');
    var txt = document.createTextNode(opts[i].text);
    li.appendChild(txt);
    ul.appendChild(li);
  }
  // add the ul to the form
  obj.parentNode.appendChild(ul);
}

You might be thinking "now what happens if there is a selected <option> already?" We can account for this by adding another loop before we create the <li>s to look for the selected <option>, and then store that value in order to class our selected <li> as "selected":

…
  var opts = obj.options;
  // check for the selected option (default to the first option)
  for (var i=0; i<opts.length; i++) {
    var selectedOpt;
    if (opts[i].selected) {
      selectedOpt = i;
      break; // we found the selected option, leave the loop
    } else {
      selectedOpt = 0;
    }
  }
  for (var i=0; i<opts.length; i++) {
    var li = document.createElement('li');
    var txt = document.createTextNode(opts[i].text);
    li.appendChild(txt);
    if (i == selectedOpt) {
      li.className = 'selected';
    }
    ul.appendChild(li);
…

[Note: From here on out, option 5 will be selected, to demonstrate this functionality.]

Now, we can run this function on every <select> on the page (in our case, one) with the following:

function setForm() {
  var s = document.getElementsByTagName('select');
  for (var i=0; i<s.length; i++) {
    selectReplacement(s[i]);
  }
}
window.onload = function() {
  setForm();
}

We are nearly there; let's add some style.

Some clever CSS

I don't know about you, but I am a huge fan of CSS dropdowns (especially the Suckerfish variety). I've been working with them for some time now and it finally dawned on me that a <select> is pretty much like a dropdown menu, albeit with a little more going on under the hood. Why not apply the same stylistic theory to our faux-<select>? The basic style goes something like this:

ul.selectReplacement {
  margin: 0;
  padding: 0;
  height: 1.65em;
  width: 300px;
}
ul.selectReplacement li {
  background: #cf5a5a;
  color: #fff;
  cursor: pointer;
  display: none;
  font-size: 11px;
  line-height: 1.7em;
  list-style: none;
  margin: 0;
  padding: 1px 12px;
  width: 276px;
}
ul.selectOpen li {
  display: block;
}
ul.selectOpen li:hover {
  background: #9e0000;
  color: #fff;
}

Now, to handle the "selected" list item, we need to get a little craftier:

ul.selectOpen li {
  display: block;
}
ul.selectReplacement li.selected {
  color: #fff;
  display: block;
}
ul.selectOpen li.selected {
  background: #9e0000;
  display: block;
}
ul.selectOpen li:hover,
ul.selectOpen li.selected:hover {
  background: #9e0000;
  color: #fff;
}

Notice that we are not using the :hover pseudo-class for the <ul> to make it open, instead we are class-ing it as "selectOpen". The reason for this is two-fold:

1. CSS is for presentation, not behavior; and
2. we want our faux-<select> behave like a real <select>, we need the list to open in an onclick event and not on a simple mouse-over.

To implement this, we can take what we learned from Suckerfish and apply it to our own JavaScript by dynamically assigning and removing this class in ``onclickevents for the list items. To do this right, we will need the ability to change theonclick` events for each list item on the fly to switch between the following two actions:

1. show the complete faux-<select> when clicking the selected/default option when the list is collapsed; and
2. "select" a list item when it is clicked & collapse the faux-<select>.

We will create a function called selectMe() to handle the reassignment of the "selected" class, reassignment of the onclick events for the list items, and the collapsing of the faux-<select>:

As the original Suckerfish taught us, IE will not recognize a hover state on anything apart from an <a>, so we need to account for that by augmenting some of our code with what we learned from them. We can attach onmouseover and onmouseout events to the "selectReplacement" class-ed <ul> and its <li>s:

function selectReplacement(obj) {
  …
  // create list for styling
  var ul = document.createElement('ul');
  ul.className = 'selectReplacement';
  if (window.attachEvent) {
    ul.onmouseover = function() {
      ul.className += ' selHover';
    }
    ul.onmouseout = function() {
      ul.className = 
        ul.className.replace(new RegExp(" selHover\\b"), '');
    }
  }
  …
  for (var i=0; i<opts.length; i++) {
    …
    if (i == selectedOpt) {
      li.className = 'selected';
    }
    if (window.attachEvent) {
      li.onmouseover = function() {
        this.className += ' selHover';
      }
      li.onmouseout = function() {
        this.className = 
          this.className.replace(new RegExp(" selHover\\b"), '');
      }
    }
  ul.appendChild(li);
}

Then, we can modify a few selectors in the CSS, to handle the hover for IE:

ul.selectReplacement:hover li,
ul.selectOpen li {
  display: block;
}
ul.selectReplacement li.selected {
  color: #fff;
  display: block;
}
ul.selectReplacement:hover li.selected**,
ul.selectOpen li.selected** {
  background: #9e0000;
  display: block;
}
ul.selectReplacement li:hover,
ul.selectReplacement li.selectOpen,
ul.selectReplacement li.selected:hover {
  background: #9e0000;
  color: #fff;
  cursor: pointer;
}

Now we have a list behaving like a <select>; but we still need a means of changing the selected list item and updating the value of the associated form element.

JavaScript fu

We already have a "selected" class we can apply to our selected list item, but we need a way to go about applying it to a <li> when it is clicked on and removing it from any of its previously "selected" siblings. Here's the JS to accomplish this:

function selectMe(obj) {
  // get the <li>'s siblings
  var lis = obj.parentNode.getElementsByTagName('li');
  // loop through
  for (var i=0; i<lis.length; i++) {
    // not the selected <li>, remove selected class
    if (lis[i] != obj) {
      lis[i].className='';
    } else { // our selected <li>, add selected class
      lis[i].className='selected';
    }
  }
}

[Note: we can use simple className assignment and emptying because we are in complete control of the <li>s. If you (for some reason) needed to assign additional classes to your list items, I recommend modifying the code to append and remove the "selected" class to your className property.]

Finally, we add a little function to set the value of the original <select> (which will be submitted along with the form) when an <li> is clicked:

function setVal(objID, selIndex) {
  var obj = document.getElementById(objID);
  obj.selectedIndex = selIndex;
}

We can then add these functions to the onclick event of our <li>s:

…
  for (var i=0; i<opts.length; i++) {
    var li = document.createElement('li');
    var txt = document.createTextNode(opts[i].text);
    li.appendChild(txt);
    li.selIndex = opts[i].index;
    li.selectID = obj.id;
    li.onclick = function() {
      setVal(this.selectID, this.selIndex);
      selectMe(this);
    }
    if (i == selectedOpt) {
      li.className = 'selected';
    }
    ul.appendChild(li);
  }
…

There you have it. We have created our functional faux-. As we have not hidden the originalyet, we can [watch how it behaves](files/4.html) as we choose different options from our faux-. Of course, in the final version, we don't want the original to show, so we can hide it byclass`-ing it as "replaced," adding that to the JS here:

function selectReplacement(obj) {
  // append a class to the select
  obj.className += ' replaced';
  // create list for styling
  var ul = document.createElement('ul');
…

Then, add a new CSS rule to hide the

select.replaced {
  display: none;
}

With the application of a few images to finalize the design (link not available) , we are good to go!

And here is another link to someone that says it can't be done.

For MySql:

UPDATE table1 JOIN table2 
    ON table1.id = table2.id
SET table1.name = table2.name,
    table1.`desc` = table2.`desc`

For Sql Server:

UPDATE   table1
SET table1.name = table2.name,
    table1.[desc] = table2.[desc]
FROM table1 JOIN table2 
   ON table1.id = table2.id

All solutions I've seen here rely on selecting an already comparable field. If one needs to compare in a different way, though, this solution here seems to work generally, for something like:

somedoubles.Distinct(new LambdaComparer<double>((x, y) => Math.Abs(x - y) < double.Epsilon)).Count()

You have to loop through each element in the 2d-array, and get the nth column.

    function getCol(matrix, col){
       var column = [];
       for(var i=0; i<matrix.length; i++){
          column.push(matrix[i][col]);
       }
       return column;
    }

    var array = [new Array(20), new Array(20), new Array(20)]; //..your 3x20 array
    getCol(array, 0); //Get first column
